DESCRIPTION
●The OPA549 is a low-cost, high-voltage and high-current operational amplifier ideal for driving a wide variety of loads. This laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high output voltage and current.
●The OPA549 operates from either single or dual supplies for design flexibility. The input common-mode range extends below the negative supply.
●The OPA549 is internally protected against over-temperature conditions and current overloads. In addition, the OPA549 provides an accurate, user-selected current limit. Unlike other designs which use a power resistor in series with the output current path, the OPA549 senses the load indirectly. This allows the current limit to be adjusted from 0 A to 10 A with a resistor or potentiometer, or controlled digitally with a voltage-out or current-out digital-to-analog converter (DAC).
